As organic gems, pearls are vulnerable to chemicals found in cosmetics, hair spray, and perfume. To preserve the lustre of your pearls, always put on your jewellery after applying makeup and styling products. Pearls can also be harmed by perspiration. Before placing your pearls back into the jewellery box, wipe them gently with a soft cotton or bamboo cloth.

From time to time, check the clasps or screws holding your jewellery together. With frequent wear, even well-cared-for pearls may loosen and will require restringing. If they're worn consistently, pearl strands should be restrung every one to two years.

Contact with other jewellery may scratch pearls. Avoid tangles by fastening clasps and laying each jewellery piece in a separate compartment of your jewellery box. When travelling, use a protective jewellery pouch or wrap each item in a soft cloth. When stored too long, pearls can dehydrate. The oils from our skin help rehydrate pearls and maintain their lustre and colour, so wear them frequently.

Never use an ultrasonic cleaner on your pearls. It can damage their nacre. Occasionally, wipe your pearls gently with a cloth dipped in mild, soapy water. Then, rinse the cloth in fresh water and wipe the pearls clean. Dry them with a soft cloth, such as cotton or bamboo. If pearls come into contact with an acidic substance such as fruit juice, vinegar, or other chemicals, immediately clean them with a soft cloth. Be careful not to submerge your pearls in water, as this will weaken the silk thread.
